ARM Architecture Reference Manual The purpose of this manual is to describe the ARM instruction set architecture, including its high code density Thumb® subset, and three of its standard coprocessor extensions: • The standard System Control coprocessor (coprocessor 15), which is used to control memory system components such as caches, write buffers, Memory Management Units, and Protection Units. • The Vector Floating-point (VFP) architecture, which uses coprocessors 10 and 11 to supply a high-performance floating-point instruction set. • The debug architecture interface (coprocessor 14), formally added to the architecture in ARM v6 to provide software access to debug features in ARM cores, (for example, breakpoint and watchpoint control).-ARM Architecture Reference Manual The purpose of this manual is to describe the ARM instruction set architecture, including its high code density Thumb® subset, and three of its standard coprocessor
